450650 divided by 43 
The aim is to understand the frequency of 43 in 450650.

Step 1:
If we divide 4 by 43, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 43

Moving on to step 2:
43 goes into 45 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 43 from 45 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 43

Step 3:
43 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 20, we end up with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 43

Let's proceed to step 4:
The number 43 fits into 206 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we subtract 172 from 206, we get 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 43

On to step 5:
43 can be fit into 345 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 1048.0
Deduct 344 from 345 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 43

Step 6:
If we divide 10 by 43, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10480.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 43 fits into 100 2 times, leaving a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 10480.2
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 10480.23
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 43 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 10480.232
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10480.2325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
If we divide 250 by 43, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10480.23255
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 10480.23255, with a leftover of 3.5e-05.
